Cedar vs. Thermowood Barrel Saunas
Wood choice affects price, appearance, aroma, and long-term maintenance. Both are legitimate, widely used choices — the right one depends on your priorities.
| Criteria | Cedar | Thermally Modified Wood (Thermowood) |
|---|---|---|
| Natural rot/insect resistance | High — naturally occurring oils resist decay | High — achieved through a heat-treatment process rather than natural oils |
| Typical cost | Premium — generally the more expensive option | More affordable — often a lower-cost softwood before treatment |
| Aroma | Distinctive natural cedar scent, especially when heated | Milder scent; some of the wood’s natural aromatic compounds are altered by the heat process |
| Stability/warping | Good dimensional stability | Very good — the thermal modification process specifically improves dimensional stability |
| Environmental sourcing note | Often Western Red Cedar; sourcing/sustainability varies by supplier | Often a fast-growing softwood (e.g. pine, spruce) made durable through processing rather than old-growth harvesting |
Which should you choose?
Choose cedar if the classic cedar aroma and traditional look matter to you and the higher price fits your budget. Choose thermowood if you want strong durability and stability at a lower price point and don’t mind a milder scent.
